Learning is affected by the total situation. This total situation is dependent upon a number of factors. Some are external while others are internal. Among the external factors to the classroom situation, we may mention two important factors- a) Heredity and b) Environment. Environment also can be divided into (i) Status of the home, (ii) Social condition, (iii) mother institution etc. A classroom teacher can neither change nor increase heredity. Of course, he can use it and develop it. Some children are very rich in heredity endowment while others are very poor. The native intelligence is different in individuals. Children vary also in particular activities. Physical condition and home condition also matter. Bodily weakness, chronic illness, malnutrition, fatigue and bad health are a great hindrance in learning. Social conditions also affect the learning. The infrastructure of the mother institution also plays a vital role in learning.
